26.7ct Tanzanite & Diamond Cluster Pendant – 18ct White Gold

Product Details

An exceptional 26.7 carat tanzanite and diamond cluster pendant, centred on a striking oval mixed-cut tanzanite of remarkable depth and colour, graded AAAA. The gemstone displays a rich medium-to-dark blue-violet hue, selected for its exceptional saturation and brilliance. Please note: the chain is not included.

Investment & Rarity
Fine tanzanites of this size and calibre are becoming increasingly difficult to source, particularly in larger carat weights with strong saturation and clarity. As mining output continues to decline, stones of this quality are considered highly desirable among collectors and connoisseurs.

Surrounding the centre stone is an elegant halo of forty-eight round brilliant-cut diamonds, meticulously claw and grain set in a refined three-row oval cluster head. The pendant is finished with a hinged, grooved “V”-shaped bail, allowing it to sit beautifully when worn.

Crafted in white gold, the pendant is stamped “18K” and has been professionally tested as 18ct gold. Its presence is both luxurious and substantial, offering outstanding visual impact while remaining timeless and wearable.

This pendant has been independently assessed by a qualified gemmologist, confirming the tanzanite’s exceptional quality and natural origin alongside detailed diamond assessment. Independent WGI laboratory certification can also be arranged at the buyer’s request.
